Good point, which you're probably make for a bad reason -- i.e. to get people to vote Republican in 2014.
The truth is, global capitalism is facing "structural" unemployment, not only in the USA, but also in Western Europe and even China, to some extent. Obama's economic stimulus program of 2009 -- which was a good idea, but much too small -- has softened the impact of capitalist structural crisis on the American workforce, but it hasn't eliminated it.
Democrats, Republicans, and even most "left liberal" economists tended to downplay this problem, because they don't want to get at its source -- modern capitalism itself.
To give the "left liberal" economists some credit, however, they're correct in arguing that GOP-style "austerity" is not going to fix the problem.
Of course, the ultimate problem == which the left liberals don't touch -- is that there is too much capitalist cash awaiting investment and not enough places for the capitalists to invest it, which means that a huge fraction of it goes to waste -- or gets "invested" in corporate mergers & acquisitions, which add nothing to real-world economic production & generally destroy jobs.
Much of the rest of this extra capital gets invested in "financialization" of some sort -- in pure speculation in derivatives, junk bonds, etc. etc. that merely piles up debts for the future, without producing either new jobs or new production. But you can't attack the surplus cash held by investors without questioning the logic of capitalism itself -- which is taboo in US politics. So the left-liberals mostly don't go there.
Where the "left liberal" economists are correct is in pointing out that "austerity" politics -- conservative demands to reduce the US national debt -- tend to make the problem worse. By slashing government spending on poor people, and by taking away safety net programs in order to reduce workplace security and force Americans to accept jobs for lower wages, the conservative austerity mongers are reducing the total income of the "99 percent," and this means reducing total consumer purchasing power in the economy.
In a "healthy" capitalist economy -- to the extent this isn't a contradiction in terms -- the working class and the poor spend huge amounts of money on daily necessities and some luxuries as well. This spending creates a market for what capitalist companies can produce, and feeding that market with goods & services provides opportunities for capitalist investors, big and small.
When you shrink the total income of the 99 percent and reduce consumer spending, however, the markets for what the system produces have to shrink. This shrinkage of markets and consumer demand causes some companies to go bankrupt, forces others to reduce hours and production levels, and shrinks the opportunities open to investors. "Austerity" capitalist-style therefore usually generates recession -- which destroys even more jobs.
